NFL defenses may have figured out a way to stop Kelly’s ‘blur’ offense but the NFL also adopted some of his ideas and methods.

While at Oregon, Kelly made trips to New England to talk about the hurry-up offense with Bill Belichick and his staff. Belichick and Kelly have become good friends and there is a possibility, however remote, that Kelly could slide into the OC spot if current Patriots OC Josh McDaniels gets another head coaching gig with, ironically enough, the San Francisco 49ers.

Many criticized the offense and in it’s purest form wasn’t very successful at the NFL level. However aspects of the offense have made it into just about every current NFL offense. Using the pass to set up the run, single back sets and having wide receivers read the coverage along with the quarterback.

Kelly’s offense and training methods are seeing a similar bubbling up across the league. Kelly embraced sports science and employed a ‘sport science coordinator’while with the Eagles. Other NFL teams have begun to embrace the idea of maximizing athletes performance after Kelly blazed the way.

Teams have also incorporated some zone read plays, allowed their quarterback to run more often, and of course using the hurry-up or no huddle offense throughout the game instead of just at end of a half.

While Kelly may not have revolutionized the game like the late Bill Walsh did so many years ago, he did influence it significantly like Mouse Davis did back in the late 80’s/early 90’s. Kelly’s NFL career will be judged by wins and losses but he has contributed much more than that.
